Are these turbo to manifold bolts for real?

[MojaveJoe]

I have never seen any exhaust system bolt or nut that went from FULL torque to ZERO torque in less than 1/8 th turn, but all four of these did.



About to reinstall all the parts I loosened to put in my pyro thermocouple, and wondering if anti-seize lube is in order on these studs/nuts. I put it on the pyro bushing, but Im thinking if all they are depending on to hold this flange connection is brute torque (nut against flange, no lock washer) maybe anti-seize would make the connection too loose?



Any thoughts or suggestions?



And does anyone know the torque spec for the flange bolts.



Just dealing with my problems one at a time

Thanx,

Joe

If it were me, I'd use anti-sieze. But then, I use the stuff on everything (comes from having owned 15-20 year old cars where every fastener was rusted on).



Service manual says:



Turbo flange studs = 18 ft. lb.

Turbo mounting nuts = 32 ft. lb.

I did my pyro intsall last week and was amazed at how tight they were for just a wee little bit. My years of working on cars and equipment taught me well and have had to regrow several square inches of hide. I came through without a scratch but this has got to be a great opportunity to let some of the red stuff escape if your not being careful.

I hear ya Darren. Think I will leave the anti-seize off these new nuts. Afraid they will loosen up if I don't let them seize up *L*



Thanks for the info rb. Torque upon removal was about 75# minimum. So much for the Mexican pipe wrench (Oops! I mean Torque Wrench )



And you're right about that MM
